    Mining in central Florida has been moving south since Florida phosphate mining began. As sites mine out, the draglines move to where the contiguous deposit of phosphate pebble is found. The further south one travels, the quality of the rock mined is lower, bringing with it greater technological challenges for the industry.

    Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid. It is that acid that is used to make fertilizer. Most of the phosphoric acid produced, about 90%, is used to make

    Orthophosphates are especially important among the various phosphates because of their key roles in biochemistry, biogeochemistry, and ecology, and their economic importance for agriculture and industry. The addition and removal of phosphate groups (phosphorylation and dephosphorylation) are key steps in cell metabolism.

    Phosphate minerals contain the tetrahedrally coordinated phosphate (PO 4 3−) anion along sometimes with arsenate (AsO 4 3−) and vanadate (VO 4 3−) substitutions. Chlorine (Cl −), fluorine (F −), and hydroxide (OH −) anions that also fit into the crystal structure.. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.

    The Process of Phosphate Mining in Florida Phosphate mining in Florida is a strip-mining process. Overburden, the layers of material above the phosphate, is removed to expose the phosphate reserve (matrix). Before mining, exploratory cores are taken to measure the depth of the overburden and the thickness of the phosphate matrix. This coring

  • Florida Phosphate Mining History Florida Industrial and

    Florida phosphate mining dates back to the first hard rock deposits found near Hawthorne in Alachua County in 1883. Endurance was imperative in the early years when phosphate mining was done with wheelbarrows, picks and shovels. Next came mule-drawn scrapers. Mechanized excavation began between 1900 and 1905 with steam shovels. Early steam shovels held only one cubic yard of earth,

  • Mining The Phosphate Risk

    In Florida, the phosphate rock is extracted by a process referred to as strip-mining. Unlike mining in other states, phosphate deposits are found closer to the surface, about 30-40 feet below ground. Sandy topsoil, also known as overburden, is removed by large digging machines called draglines. The draglines can remove from 20 65 tons of overburden per dig, leaving 215 ft.-wide paths behind. The phosphate is

    Previously, significant amounts of rock were shipped to China, where it was processed into phosphate fertilizer. The majority of phosphate mining in Florida is done in the Peace River watershed. Phosphate mining companies use draglines to remove surface soils up to 60 feet (18.29 m) deep over thousands of contiguous acres. Once land is mined, state law requires that it be reclaimed.
